These might need STARTTLS explicitly disabled in the msmtp config file though

A user reports notifications not working on their setup because there is
no display id  contained in the `ps`/`pgrep` output  concerning the Xorg
process.

This commit checks if there's a display server running at all, and if so
it sends notifications even if there's no display id.

Fix notifications on Wayland-based environments

remove old vars like pass_prefix, muttdir
reorder mailbox detection to find inbox case and later delim
offline delim set to _ which should avoid most issues

Fix duplicate mailsync notifications

mailsync: Check for ZDOTDIR when looking for environmental variables inside .zprofile and .zshrc

inside .zprofile and .zshrc.

~/.profile is not necessarily present when using zsh for login and
setting $ZDOTDIR in ~/.zshenv

Fix: `macro index o` overlapping with next account

When the transition is made from an offline profile to an online
profile, there is still someone else's macro - side effects...
Variables, macros, and so on must be taken-into-account
**symmetrically** with any of the `mutt-wizard`'s profiles.

🐛 Fix ProtonMail log-on failure when adding a new account

Part 2 of 2 for "Log-on not successful" bug when using ProtonMail.

The curl login check uses the imap(s) protocol, which means it will use
the default ports. However, when using ProtonMail, these ports are
different (namely 1143 instead of 993).

We now use the port variable in the curl login command, defaulting to
993 when the port was not overridden.

The port variable was already set when the ProtonMail flag (-p) was set.

Part 1 of 2 for "Log-on not successful" bug when using ProtonMail.

The curl login check defaults to `imaps` when `protocol` isn't set.
Because ProtonMail isn't using any TLS, we have to use the `imap`
protocol.
The `protocol` variable was never set, so now we set it when the
ProtonMail flag (-p) is set.
